Referring to the drawings there is shown in Fig. 1, in the rearelevation, a series of syrup or flavor liquid reservoirs 1, 2, 3 and 4,which may be increased to any desired number, within practical limits ofthe apparatus; each containing one of a series of different flavoringliquids or other liquid ingredients of the beverage to be dispensed.Each of the syrup reservoirs is connected by means of a suitable pipeconnection 5, 6. 7 and 8 respectively, to a corresponding series ofmeasuring and ejecting pumps 9, 10, 11 and 12, one of which is shown indetailed section in Fig. 2. The Havering liquid or other liquidingredient normally fills the pipes 5, 6 and 7 or in the particularillustration shown in Figs. 2 and 9, the pipe 6; and also fills thecorresponding` ejector chamber 13, to which it is connected through theball check valve 14, (Fig. 2) which permits the flow of the liquidtowards the chamber 13 and prevents any reversa-l of the i'iow, by theseating of the check ball 15, on the valve seat 16 of said check valve.The liquid contained in the tank also lls therefore the pipe orpassageway 18 in the particular illustration shown in Fig. 2, in amanner similar to passageways 17, 19 and 20 illustrated in Fig'. 1. Eachof the passageways 17, 18, 19 and 20 terminate in a corresponding seriesof check valve devices 21, 22, 23 and 24@ shown in Figs. 1, 2, 9 and 10,which are connected to, and carried by, the wall 25 ofthe mixing chamber26 of our novel mixing and dispensing valve mechanism 27. Each ofthecheck valve devices 21, 22, 23 and 24- is provided with a check ball ora suitable valve plate 23, which is normally held seated against thevalve seat 29, in a yieldable manner, by means of the helicalcompression spring 30 surrounding` the valve stein 31, and interposedbetween the upper plate 32 carried by said valve stem 31, and thestationary spring seat portion 33 of such check valve devices. Thus theweight of the flavor syrup or other liquid ingredient which 'normallyfills the pipe G and chamber 13 as well as the passageway 13, isretained within said passageways by means of the yieldable valve ball 2Sheld against the valve seat 29 in a yieldable manner by means of thespringl 39 or other suitable tensioning means. Tvlhenever the piston311- of the ejector pump 10 is forced forward in the direction of thearrow 35, the check ball 15 being thereby forced up against the valveseat 16, causes the piston 34 to Til ill)

loo

force a quantity of ilavoring liquid through they-ieldable check device22 into the mixing chamber The quantity of flavoring liquid thusdischarged or forced into the mixing chamber 26 by the piston 34, isequal therefore to the volume displacement of the piston 34, which inpractice is substantially uniform, since the stroke of the piston is thesame at all times.

In order to retain the measured quantity of the flavoring liquid withinthe mixing chamber 26, after it has been discharged thereinto, andbefore it is mixed with a suitable quantity of carbonated water, thereis provided a check ball valve 36, seated on the valve seat 37 bygravity, the ball 36 being of such weight that it will not be disturbedor removed from said valve seat 37 by the entrance or discharge of theiavoring liquid into the mixing chamber 26, and yet of such weight andbulk that it will be readily removed from the valve seat by the force ofthe carbonated water as it is projected into the mixing chamber 26.

In the rear 0f the mixing chamber 26y integral with the wall 25 thereof,is the stationary portion 38 of the mixing valve 27, into which are led,a series of live pipes 4l, 42, 43, 44 and 45, which interconnect thecorresponding` series of stationary port holes 5l, 52, 53, 54 and 55 inthe face 39 of the stationary portion 38 fof the valve, with the Variouselements of the carbonating apparatus. Thus the port 5l of thestationary portion of the valve is permanently connected, through thepipe 4l, with the storage tank 8O containing a supply of compressedcarbonating gas or carbondioxide. The port 52 is connected through thepipe 42 to the discharge end of the charging or carbonating battery 8l.The port 53 is ,permanently connected, through the pipe 43, with thereceiving end of the charging or carbonating battery 81. The port 54,through the pipe 44, is connected with the top of the measuring chamber82; and lastly the port 55 is connected through the pipe 45, to themanifold 83 of the charging or carbonating battery 81, at a pointbetween the measuring chamber 82 and the series of absorption chainibers 84, 85 and 86.

The movable or disc portion 87 of the valve 27, revolved by means of thevalve stem 83, and held in operative contact with the face 39 of thestationary portion 38 of said valve, is provided on its contacting face89 with a number of port holes 6l to 67 inclusive so located withrespect to the port holes 5l to 55 inclusive in the stationary portion38 of the valve 27, and so provided with passageways interconnecting thevarious port holes 6l to 67 inclusive in said disc or movable portion87, as to properly and differently connect up the various pipes 4l to 45inclusive and the mixing chamber 26, in two different angular positionsof said disc, namely in the closed and in the open position thereofrespectively. The

closed position of the valve shown in Fig. 1l, and the open positionthereofI shown in Fig. l2, are approximately 45 degrees apart, in thedirection indicated by the arrow 90 in Fig. 12. Accordingly the ports 6land 63 are interconnected by the passageway 7l shown in Figs. 1l, l2 and13 particularly; the ports 62 and 65 are interconnected by means of thepassageway 72 as shown in particular in Figs.

ll, l2 and l5; the port 64 passes straight' through the disc 87 throughthe passageway 73, directly into the mixing chamber 26 while the ports66 and 67 are connected by means of the passageways and respectix elj,Tthrough an axial passageway 78 in the stem 88 of the valve disc 87, anda plurality of radially disposed discharging openings 79, with themixing chamber 26. Thus in the closed position of the valve, as shown inFig. 1l, the ports 6l and 65 inclusive correspond and coincide with theports 5l to 55 inclusive in the stationary portion 38 of the valve 27.It will be seen that in this position of the valve, the carbonating gasfrom the -tank 8O is conveyed directly, through the pipe 4l to the ports5l, 6l and then through the passageway 7l through the ports 63 and 53back through the pipe 43 into the first absorption chamber 86 of thecl'iarging battery 8l, thus exerting a full pressure of the gas on theseries of absorption chambers 84, 85 and 86. In this closed position ofthe valve disc moreover, the pipes 42 and 45 are interconnected throughthe ports 52 and 55, and 62 and 65 and the passageway 72, so as topermit the water to flow' freely from the last absorption chamber 84into the measuring chamber 82. Lastly, in this closed position of thevalve disc 87 the pipe 44 from the top of the measuring chamber 82 isconnected through the passageway 74 and the corresponding ports to 64,to the mixing chamber 26 of the valve 27. The charging or carbonatingoperation, which takes place during the olf or closed position of thevalve 27 is as follows :l`he gas enter ing the absorption chamber 86,from the tank 80, through the pipes 4l and 43 and through the valve 27as mentioned hereinbefore, passes through the water contained in saidabsorption chamber 86, and at the same time forces the water out fromthe chamber 86 through the passageway 91 in the manifold 83, into thevertical spray pipe 92 and forcing the water, mixed with gas, out'through the perforated funnel 94, in the form of a spray, which thendescends to the bottom of the chamber 85, through the mixing screen 95.The water then continues to travel on through the successive absorptionchambers 84, urged by the pressure of the gas supplied from the pipe 43,through the series of passageways 96, in the common manifold 83 and thecorresponding series of vertical spray tubes 97 extending into saidabsorption chambers 84. The water thus fully charged with thecarbonating gas, in its passage through the series of absorptionchambers, enters into the passageway 98 in the manifold 83, from whenceit will pass into the measuring chamber 82, either by raising the checkball 99, which is provided on the valve seat 100, to prevent the retreatof the carbonating water from the measuring chamber into the absorptionchambers, or through the pipe. and the ports 55, and 52, and 65 and 62,and through the pipe 42 and passage way 101 as shown particularly in 4.As the measuring chamber 82 is filled with the carbonated water,entering the same through the bottom thereof, the gas originally fillingthe measuring chamber 82 passes out through the pipe 44 and the ports 54and 64 and the passageway 74, into the mixing chamber 26 of the valve27. When however the carbonoted water has risen to the height of thecheck valve ball 102, contained within the cage 103, it lifts and forcesthe check valve ball 102 against the corresponding valve seat 104,thereby shutting olf the pipe 44, and preventing the exit of thecarbonated water from the measuring chamber 82, so as to retain withinsaid chamber 82 while the valve 27 is closed, or in the off position, a.premeasured and fixed quantity of fully charged or carbonated water.rllhe check valve ball 105, normally held seated on the valve seat 106by the force of gravity, is provided for the ,purpose of shutting offthe fresh water intake port 107, when the pressure of the carbonated gasis exerted on the series of absorption chambers, namely during the offposition of the control valve 27. Upon revolving the valve disc 89 ofthe valve 27, in a righthand direction indicated by the arrow 90, fromthe off position shown in Figure 11, into the on position shown inFigure 12, namely the open or discharging position; the following cycleof events talies place :The carbonating gas (CO2) from the storage tank80 passing through the pipe 41 and port 51, now instead of passing tothe top of the first absorption chamber 86, as in the off, charging orclosed position of the valve 27, passes through the movable port 63, thepassageway 71, and the ports 61 and 54, and through the pipe 44 into thetop of the measuringchamber 82, and eX- erts the full pressure of thecarbonating gas on the premeasured quantity of carbonated watercontained in said measuring chamber 82. rlhe pressure of the gas thusexerted on the water of the chamber 82 seats the check valve ball 99tightly on the valve seat 100` thereby shutting` oif the measuringchamber from the absorption chambers, and forces the measured quantityor charged water through the passageway 101, the pipe 42, ports 52 and67, and through the passageways 77 and 78, out through the discharfeapertures 79 into the miXin chamber 26. The force of the carbon atedwater. imnelled by the presi-mrc ef the gas from tank 80 dischargingthrough the series of radial discharge openings 79, raises the checkvalve ball 36, resting on the valve seat 87, thereby permitting thedischarge of the carbonated water now thoroughly mined with theflavor-ing liquid previously deposited in said mixing chamber 26,through the discharge nozzle 108. ln this position of the valve dise 89moreover, the port 66, coinciding with the port 58, connects the firstabsorption chamber 86, through the pipes 43 and the passageway 76, withthe axial passageway 78, at a point a slight distance in front of thepoint where the passageway 77 meets the passage way 78. Thus thecarbonated water passing through the passageways 77 and 78 and thedischarging apertures 79 with great velocity, due to the pressure of thecarbonating gas urging the same, produces a jetting action on the gascontained within the passageway 76; hence producing suction in the pipe48. Since the ball check` valve 98 prevents retreat of any wat-er or gasfrom the absorption chamber 85, back into the absorption chamber 86, thesuction created by the etting action of discharging carbonated waterthrough the passageways 77 and 78, reduces the pressure within thechamber to a point where the fresh supply of water connected to thesupply port 107, raises the chech valve ball 105 from the valve 106, andthus enter-v and refills absorption chamber 86 with a fresh supply ofwater.

Upon resetting, or turning back the valve disc 87 into the off or closedposition shown in Fig. 11, the cycle of carbenating or chargingoperations and events is again repeated, and a quantity of water isagain charged or carbonated, and is caused to refill the measuringchamber 82, which has been emptied during the discharging or on7position of the valve, by relieving tbe within the measuring chamber 82the gas being allowed to pass olf from the top of the chamber; throughthe pipe 44; the check valve ball 102 thereafter shutting off said pipe44 from the measuring chamber, when the liquid has reached the ball.

The cycle of epcrations between the 'flavoring liquid or syrup measuringdevices and the cup supply device. is as follows z-l`irst a givenquantity of flavoring liquid or syrup is forced into the mixing chamber26, secondly the cup is deposited beneath and in vertical alignment withthe nozzle 108, and lastly t-he carbonated water, mixed with theflavoring liquid, is discharged through the nozzle 108 into the cupbeneath the latter.

In order to permit the automatic vending of the mixed beverage,independently of a salesman or operator, as is customary in dispensingbeverages over the counter, the various mechanisms hereinbeforedescribed, and those to be described hereinafter, are all mountuluponand bach' ot a vertical panel 109 which may be of any suitable finishedmaterial, such as is commonly employed in soda fountain construction,and there is provided a novel series of locking and releasing devicesfor the syrup ejectors, for the carbonatedwater discharging and mixingvalve, for the paper cup supply mechanism 110, as well as for theserving platform 111; all released in proper succession by a single coinof the proper denomination dropped into the coin slot 112. Thus in thenormal position of the apparatus, before a coin has been deposited inthe coin slot 112, the syrup plunger knob 113 may be forced inwardly,against the tension of the spring 114, without however actuating thesyrup piston 34, since the plunger 134 enters freely the hollow rod 115,ofthe ejector 10. Similarly the valve stem 88 carrying the crank handle116, as well as the locking arm 117, is locked against any movement bymeans if a latch mechanism shown in Figs. 2, 6, and 8, which is onlyreleased by the dropping of the coin from the syrup ejecting mechanism,after the same has passed through a full cycle of operations with saidcoin, into the coin box 118, carried by locking arm 117. Similarly thepaper cup supply mechanism 110, which may be of any usual constructionnow found on the market, operated by the lever 119, is not brought intoaction unless the arm 117 is actuated, since the arm 117 and the arm 119are operatively interconnected by means of the spring or other suitableconnection 120. The serving platform 111, being pivotally mounted at apoint 121, on the hinge door 122 carried on the hinges 123, is in turnlocked in the closed position shown in Fig. 2, by means of the catch 124engaging the slight notch 125 in the base 126, the platform 111 beingretained in the normal raised position by one of several fiat springs127, or by any other suitable yielding means.

Upon depositing the coin of the proper denomination in the coin slot112, the same is guided by means of the chute 128, into the coin box129, which is shown in detail in Fig. 5 as well as in Fig. 2. The coinbox 129 is carried rigidly on the end of the hollow piston rod 115 andtravels with the latter, and is provided with the vertical slot 130,open at its bottom. In the coin receiving position of the coin box 129,the same is superimposed upon the narrow portion 131 of aI coin gaugingand retaining plate 132, fixed in a stationary manner on the panel 109,as shown in Fig. 2, which narrow portion 131 is of a width justsufficient to prevent the coin of the proper denomination from fallingthrough, yet wide enough to permit any smaller coin to drop through.After the coin 133, indicated by the dotted circle in Fig. 5, has beendropped into the coin box 129, it blocks the passage of the plunger rod134 through the coin box 129. The plunger 134 upon being forced inwardlythus encounters and engages the coin 133, and by means of suchengagement with the coin 133, forces the coin box 129, and hence thepiston rod 115 and the piston 34 rearwardly. in the direction of thearrow 35, thereby forcing the predetermined quantity of syrup or otherYliavoring liquid into the mixing chamber 26 ofthe valve 27. Uponreleasing the plunger knob 113, the same is returned by the spring 114,while the piston 34 is returned by the spring 135, against thecompression of the air behind the piston 34, as the same escapes slowlythrough the vent hole 136. The tension of t-he springs 114 and 135 andthe size of the vent hole 136, are so iixed, that the plunger rod 134 isreturned much faster and therefore ahead of the piston rod 115 and thecoin box 129, so as to release its hold upon the coin contained in theslot 130, during the re: turn. The coin 133 thus freed of the plunger134, and thev coin box 129, being thus superimposed upon the wideportion 137 of the coin gauging plate 132 during the return stroke, thecoin 133 drops out of the slot 130 in the coin box 129, 'through thewide portion 127 of the plate 132, into a chute 138 positioned beneaththe plates 132, which chute guides the coin to the second coin box 118carried by the arm 117, shown in Figs. 1, 2, 6 and 8 of the dra-wings.The coin box 118 is again provided with the coin slot 139, having abottom opening 140 which is slightly smaller than the diameter of thecoin of the proper denomination, so as to retain said coin but permitany smaller coin to fall through. The coin box 118 is also provided withan edge opening 141 adapted to permit the coin 133 to drop out of thecoin box 118 when the arm 117 is tilted or swung into the extreme rightinclined position. The coin box 118 is further provided in one wallthereof, with a small plunger 142, slidably mounted in a suitablebearing opening 143, which plunger is reta-ined and held out and clearof the slot 139 by a spring 144 interposed between the head 145 of saidplunger 142 and the coin box 118. The opposed side of the coin box 118,is also provided with an opening 146 into Vwhich the plunger 142 mayenter. The latch member 147 fixed to the panel 109 and made preferablyof a thin springy material, is provided at its lower half 148 with alocking notch or ledge 149 which is in alignment with the arm 117 so asto lock the same against any movement thereof in the normal position ofthe lat-ch, while the upper portion 150 of said latch member 147 isshaped to act as a cam or wedge on the head 145 of the plunger 142,while their free ends 151 are joined so as to move in unison with eachother. Thus so long as there is no coin in the slot 139 of the coin box118, the plunger 42 will be forced into and through the slot 139, andinto the opening 146, by the cam 150, when the arm 117 is swung towardsthe right a slight dist-ance in the direction of the arrow 152, by meansof the handle 116. Thus the arm 117 soon encounters the ledge or notch149, of the latch member 143, and is stopped and locked thereby.Whenever a coin 133 is deposited in the coin box 113 in the positionindicated by the dotted circle in Fie. 6, the plunger 142 cannot latchmembers 148 and 15() away from the arm 117 in the direction of the arrow152, thereby withdrawing the ledge or notch 149 from alignment with thearm 11?, so as to permit the arm 11'( to be swung freely to the limit ofits deflected or open position. 1t is thus that the valve stem 33 islocked in 'the closed posit-ion of the valve, when there is no coin inthe coin box 113, and is released by the insertion of a coin thereinto.

During the first small fraction of the forward movement of the arm 117,in the direction of the arrow 152, after it is released by the coin 133in the coin box 113, it actuates an operating arm 119 of the paper cupdispensing and supply mechanism 110 shown in Figures 1 and 2, throughthe spring or other suitable connection 120, causing the same to drop apaper' cup 153 into the guide members 154C, which guide the paper cup inan upright position onto the serving platform 111, where it is caughtand positioned in vertical alignment with the nozzle 103, by support'155. fis the handle 116 swung completely to the open or deflectedposition, revolving the valve disc 37 into the open or dischargingposition thereof, the mixture of syrup and carbonated water dischargedthrough the nozzle 103 into the cup 153.

As the cup 153 is approximately three quarters filled with the beverageto be dispensed, the serving' platform 111 is deflected a slight amountagainst the tension of the spring 127, thereby raising the catch 1211clear of the lockingl notch 125, so as to unlock the door 122. The door122 may then be swung open, upon the hinges 123, by grasping the knob156. A return spring, lnot shown in the drawings, may be provided toreturn the door 122 into the closed position thereof, after the cup153`has been removed from the serving platform 111, so as to positionsaid platform 111 beneath the nozzle 108 in a locked position again, fora subsequent operation of the device.

lt will now be apparent that we have devised a new and useful mixedbeverage vending apparatus, which embodies the fea-tures of advantageenumerated as desirable in the statement of the invention and the abovedescription, and while we have, in the present instance, shown anddescribed a preferred embodiment thereof which will give in practicesatisfactory and reliable results, it is to s be understood that suchembodiment is susceptible of modification in various particulars withoutdeparting from the spirit or scope of the invention or sacrificing anyof its advantages.
